Who never will be missed.

As Lieberman plodded through his speech, thanking everybody from his wife to the Capitol maintenance crews, a few longtime friends trickled in.

In came John Kerry (Mass.), who bested him in the 2004 Democratic presidential primaries and then, like many Senate Democrats, endorsed Ned Lamont, who tried to oust Lieberman from his Senate seat in 2006.

In came Susan Collins (Maine), Lieberman’s Republican counterpart on the Homeland Security Committee, whom Lieberman supported over a Democrat in her 2008 reelection.

In came GOP iconoclast John McCain (Ariz.), who was close to naming Lieberman as his vice presidential running mate in 2008 – which would have made Lieberman the first man on both a Democratic and a Republican national ticket.

…

And so it was a man with few political allies who bid the chamber farewell. “I regret to say as I leave the Senate that the greatest obstacle that I see standing between us and the brighter American future we all want is right here in Washington,” he said.
